Abstract
The invention is applicable to the field of chemical fertilizers, and provides an amino acid polypeptide selenium fertilizer which is prepared from the following components in percentage by weight: 15-20% of amino acid, 5-10% of polypeptide selenium, 2-8% of an iron-containing raw material, 10-15% of a zinc-containing raw material, 2-5% of a manganese-containing raw material, 0.5-1% of a molybdenum-containing raw material, 3-8% of a boron-containing raw material, 0.05-0.1% of a synergist, 20-50% of an organic carbon liquid and 2-20% of water. The amino acid polypeptide selenium fertilizer can effectively supplement organic and micro-nutrients required by soil and crops, has high content of added components, can reduce the dosage and reduce the cost. Meanwhile, the production process of the invention has no waste discharge, environmental protection and high utilization rate of raw materials.
Description
Technical Field
The invention belongs to the technical field of chemical fertilizers, and particularly relates to an amino acid polypeptide selenium fertilizer and a preparation method thereof.
Background
According to statistics, 72% of China's soil is lack of selenium element, and almost covers all main grain producing areas in China, and more importantly, the 72% of land comprises three provinces in northeast, Shandong, Henan, Jiangsu, Zhejiang, Sichuan and the like, and almost covers all main grain producing areas in China, so that the 95% of grain selenium content can not reach the international standard. About hundreds of millions of people in China need to supplement selenium element. Selenium is an important element in human bodies, and if the human bodies lack selenium, the immunity is reduced, and more than 40 diseases such as cold, liver diseases, cardiovascular diseases, cancers and the like are easy to suffer. The northeast, the northwest and the northwest of China are zones lack of selenium in soil, the soil is lack of selenium, if people and animals eat agricultural products planted in the soil lack of selenium, a series of diseases occur, and the lives of people can be directly influenced. In addition, in order to improve productivity, farmers excessively apply nitrogen fertilizers, which causes unbalanced nutrition after soil hardening, poor disease resistance of crops and easy occurrence of various diseases, so that farmers only need to apply pesticides in large quantities and finally fall into a vicious circle.
The year-round overload planting causes the soil to be degraded, the crop nutrition is deficient, especially the deficiency of organic nutrition and trace elements, causes the quality of the planted vegetable to be low, the taste of the crop to be distorted, the year-round yield reduction, the price of agricultural products to be lower and lower, and the market to be degraded. Therefore, the development of a water-soluble organic multi-trace-element fertilizer is demanded by the market and crops.
The amino acid can be directly absorbed by plants, is an excellent nutrient for the plants, can be used for base fertilizer and additional fertilizer of various plants, and has the tendency of replacing chemical fertilizers. At present, amino acid fertilizers at home and abroad are various in variety, liquid and solid, and in recent years, amino acid-containing fertilizers imported at home and abroad are also various as follows: the total effective components of the amino acid liquid fertilizer of Lvbao, Gaumes, Edison of Japan and Indonesia in the United states are below 20 percent, and the content of the amino acid is 4 to 6 percent. And the product has high price (much higher than that in China) generally and low yield and investment in application.
The trace elements (B, Zn, Mn, Fe, Cu and Mo) are also nutrient elements for the growth of crops. Although the required amount of the fertilizer is not large, the fertilizer plays a positive role in the growth and development of various crops, and has obvious yield increasing effect and the effect of further improving the quality of the crops. With the development of agricultural production, crop varieties are continuously updated, the number of nutrient elements required to be supplemented by crops is increased, the use of trace elements is increased, the living standard of people is improved year by year, and 70-80% of the nutrient elements required to be supplemented by human bodies need to be absorbed from food. In addition, most selenium-containing fertilizers in the prior art are inorganic selenium, crops are difficult to absorb and utilize, most selenium-containing fertilizers remain in soil and pollute the soil, the inorganic selenium exceeds a certain limit amount, toxicity is generated to human bodies, and the product safety is low.
Disclosure of Invention
The invention aims to provide an amino acid polypeptide selenium fertilizer and a preparation method thereof, which are used for solving the problems of poor crop quality, insufficient functional nutrition and low yield by adding amino acid trace elements of polypeptide selenium in the form of various trace elements.
On one hand, the invention provides an amino acid polypeptide selenium fertilizer which is prepared from the following components in percentage by weight:
15 to 20 percent of amino acid,
5 to 10 percent of polypeptide selenium,
2-8% of iron-containing raw material,
10-15% of zinc-containing raw material,
2 to 5 percent of manganese-containing raw material,
0.5 to 1 percent of molybdenum-containing raw material,
3 to 8 percent of boron-containing raw material,
0.05 to 0.1 percent of synergist,
20 to 50 percent of organic carbon liquid,
2-20% of water.
On the other hand, the invention provides a preparation method of the amino acid polypeptide selenium fertilizer, which comprises the following steps:
selecting the components according to the raw material proportion of the amino acid polypeptide selenium fertilizer;
adding amino acid into the organic carbon solution, heating to 60-100 ℃, and stirring to obtain a mixture I;
adding an iron-containing raw material, a zinc-containing raw material, a manganese-containing raw material, a molybdenum-containing raw material and a boron-containing raw material into the mixture I to obtain a mixture II;
adding a synergist into the mixture II to obtain a mixture III;
